This invention relates to a surface marking roll and the like, and more particularl to a marking roll for use in connectlon wit paper machines for the marking of the paper 5 rior to drying the same but after the web lias been fully formed by passage through the presses.' Y A In one of the types oi marking rolls now inpuse`,the construction is such that diiiiculty is experienced, when the paper machine 1s running at high speeds, in obtaining proper impressions on the paper. This is due to the construction of this t pe of marking roll, wherein a number of w eels, each carrying its own bracket, are secured by means 'of the brackets to a carrier shaft mounted transversely of the paper machine, no provision being made for properly holding the wheels in constant .spaced relation or for properly synchronizing the various wheels. As a consequence, the spacing of the marks is permitted to varyand the rolls chatter and vibrate at high speeds, making imperfect impressions on the paper and occasionall tearing it.

Y Furthermore, in the usualtype of surface marking roll no provision is made for relative angular" adjustment of the marks about the periphery of the roll in order to obtain 3o zig-zagging of the marks across the paper.

' It is therefore an object of this invention to provide a surface marking roll or the like that will not chatter nor vibrate at high speeds but will under all circumstances make clear-cut and properly spaced impressions on the paper. .I

It is a further object of this invention to provide a surface markin roll comprised of separate collars' bearing t e mark, design or the like and adjustably mounted upon a shaft. with means rovided for the positive securing lof said co ars in adjusted position, both longitudinally of the shaft and with respect tothe angular relation of the marks upon adjacent collars.

Other and further important objects of lthis invention will beapparent from the disclosures in the specification and the accom anying drawings.

This invention (in a preferred form) is illustrated inthe drawings, and hereinafter.

Flgure 2 1s a sectional view taken on line.,

II- II of Figure 3 with parts in elevation. F1 rc3 is a sectional view taken on line III-III of Figure 2 with parts in elevation.

The reference numeral 1 indicates the' shaft of a surface marking roll of my inven tion having mounted thereon a pluralit of collars 2 bearing a mark, as represente by the indicia 3. As best shown in Figures 2 and 3, each of the collars 2 comprises a, ring formed with inner and outer flanges 4 and 5 respectively connected by means o-an intermediate web 6. The inner .ange 4 is bored to receive the shaft 1.' and to permit the collars 2 to be adjusted lengthwise of the shaft 1 and relative to each other. The outer iange 5 is formed with an annular groove, or recess 7, to receive a flexible band 8, preferably formed of rubber and' bearing the raised indicia 3. l

In order to provide means for securing the collars 2 in any desired position relative to each other and to the shaft -1, an elongated slot 9 is formed in the web 6 and a trans-l gated slot 9 to provide a more or less flexible tongue 11. The web 6 is strengthened im.

mediately above the slot 9 as at 12 and provided with a transverse threaded bore 13 for receiving set screws 14 and 15. A second bore 16 extends radially through the upper. ilange 5 and the thickened web portion 12L to intersect said bore 13. A short pin 17 is adapted to be positioned in the bore 16' to bearagainst the tongue 11. The upper portion of said bore 16 is threaded to receive a set screw 18, which is normally threaded -into said bore 16 until flush with the surface of the recess 7, thus closing said bore 16 and preventing a depression in said flexible band 8 at that point. The length of the pin 17 is such that its upper spherical end 19 extends slightly into the path of the bore 13.

Accordingly, when the i set screws 14 .and/ said web being provided with an elongated 15 are screwed in, the round Sends of said set screws contact the spherical head 19 of Vthe pin 17 Yand force the pin down against the tongue 11. The result is that the tongue 11 isvsp'rung downwardlfy into rictional engagement with the sur ace of the shaft A1, thus preventing relative rotation or; movement longitudinally of said shaft 1.v n

It will be a parent that the collars 2 may be readily a )usted to different positions upon the shaft 1 by merely unscrewmg the set screws 14 and 15 and moving the collarsl 2 into the desired position. In this way the spacing ,between adjacent collars may be varied or the angular advance of adjacent marks 3 may be changed at will. It should further be noted that the setV screws 14 and 15 are ,readily accessible and that no set screws come into direct contact with the shaft to score or in anyway injure the sur face of the shaft. This construction obviously makes possible greater ilexibllity in the use of marking rolls and does away with the necessity of having in storage a large number of diierent rollsto suit the various conditions under which they may be used. In the case of'rolls of my construction, a single shaft may be used for mounting v'arious sizes and types of collars as all of the collars may be made with uniform 'inside diameters to be interchangeable.

The savings that can--thus be effected are obvious, since with the interchangeable collars one vshaft will serve where formerly many complete rolls were required. Fur- Ithermore, the positive positioning of the collars onrolls of my construction prevents chattering andv vibratin of the rolls and insures t e obtaimng o clear impressions on the paper when the machine is running at lhigh speeds Without ,danger ofl tearing the pape A I am aware that numerous ch nges may be made and many details of c nstruction may be varied through a wide r ge ywithout departing from the principle of this invention, and I, therefore, do not pur ose limiting the patent granted hereon t ert slot and said inner flange with a transverse slot openin into said elongated slot adjacent one en thereof, a tongue being formed thereby `on said inner ange, a pi'n extending radially against said ton e and' set screws adapted to be threaded into angular engagement with the outer end of said pin to mcrease the bearing pressure of said pin against said tongue. -3. A collar for mounting upon the shaft of a roll, comprising a rin formed of spaced flanges and an intermediate connect-` ing web, said web bei provided with an elongated slot and said inner flange with a' transverse slot openin into said'elongated slot adjacent one end t ereof, a tongue bein formed thereby on said inner flange, the we above said elongated slot'being thickened and provided with transverse and radial intersecting bores, a pin slidably 'mounted in said radial bore and'bearing against said.

tongue and set screws threaded into said transverse borefrom opposite sides for enga'gement wlth the outer end of said pin.

wise than necessitated by the prior art.

I claim as my invention:

1. A surface marking roll, comprising a shaft, collars mounted thereon bearing a mark, design, symbol or the like, each of said collars bei slotted to form a tongue adapted to frictlonally engage said shaft i throughout its length, to thereby prevent the collar from rotating in either direction' on said shaft, and means for bringing pressure to bear against said tongue to increase the friction and maintain the collars in position on said shaft.

2. A collar 'for mountingy upon the shaft of a roll, comprising a ring formed of spaced anges and an intermediate connecting web,
